保護(hù)膜粘力分主要為:超低粘保護(hù)膜、低粘保護(hù)膜、中低粘保護(hù)膜、中粘保護(hù)膜、高粘保護(hù)膜、超高粘保護(hù)膜
1.超低粘保護(hù)膜(即微底粘):
1、保護(hù)膜對(duì)被保護(hù)材料的表面呈惰性
2、保護(hù)膜對(duì)被保護(hù)材料具有良好的粘附性能,在材料搬運(yùn)及加工過程中,保護(hù)膜不會(huì)起翹、脫落;
3、保護(hù)膜具有較好的耐候性及持粘力穩(wěn)定性,經(jīng)數(shù)日或久貼剝離力增長不顯著,易于揭去,在揭去時(shí)被保護(hù)表面上沒有殘膠留存,無留影。
4、低晶點(diǎn)
1、適宜粘性:易貼易撕;
2、剝離力穩(wěn)定:經(jīng)時(shí)變化小,即剝離力上升幅度越小越好;
3、耐候性好:在日光暴曬條件下,使用期長達(dá)半年至一年;
4、儲(chǔ)存期長:在倉庫儲(chǔ)存一年以上,品質(zhì)無變化;
5、不污染、不腐蝕:膠粘劑呈惰性,不會(huì)與被粘材料表面發(fā)生化學(xué)反應(yīng);
6、優(yōu)良的力學(xué)性能:符合用戶要求的抗張強(qiáng)度、彈性模量、伸長率等。
保護(hù)膜的主要用途:
1.五金行業(yè):電腦機(jī)殼,鍍鋅板沖壓,鋁板,不銹鋼板,鈦金板,塑鋼板,玻璃板,太陽能電池板等等。
2.光電行業(yè):LCD液晶顯示器,背光板,冷光片,薄膜開關(guān),手機(jī)屏幕等等。
3.塑膠行業(yè):ABS、PP注塑制品,PVC板材,亞克力板,儀表,塑膠鏡片,噴漆件表面保護(hù)等等。
4.印刷行業(yè):PVC、PC板,鋁板,膠片等印刷銘板表面保護(hù)等等。
5.電線電纜行業(yè):軸裝銅線、半成品、成品、打卷成品的保護(hù),可有效防止灰塵污染,有防氧化、防臟污作用。Protective film viscous force points mainly: ultra-low stick protective film, low stick protective film, high low stick protective film, adhesive protective film, protective film, high adhesive protective film
1. Ultra stick protective film (that is, the micro bottom glue) :
1, the surface of the protective film to the protected material in inertia
2, the protective film on the protected material has good adhesion performance, in the process of material handling and processing, protective film will not case become warped, fall off;
3, protective film has good weatherability and hold moisture stability, after a few days or longer stick stripping force no significant growth, easy to read, in be protected when torn off no residual adhesive left on the surface, no pictures.
4, low point
1, appropriate viscosity: easy to stick and tear;
2, stripping force stability: the change is small, the stripping force increase as small as possible;
3, weatherability ?
